Your top parses do say a lot about you, but the other noticeable thing is the only consistently ranked player other than yourself is druke. This also says a lot about the healers you heal with. Top healing parses are all well and good, but usually require cheese to some degree. Be it 3 healing normal rag, or going back after the content is no longer current and using t12 to do it. Sinestra requires you to cheese if you wish to parse well. Yes you do have a lot of nice parses, but you also have a lot of not current and cheesed parses. I'm not saying you didn't have #1 parses before they got overridden by other people, but flaunting parses for ulduar-t11 that have dates from august 2011 is just in bad taste.
Healing with 2 actions vs 1 has almost no downside, other than it requiring 2 actions vs 1. Koilie is also a priest, there are a lot more abilities they need keybound to use click->heal, I still use vuhdo's mouse over features on my priest.
Atleast 2 out of the 7 healers we rotate in and out use the click then cast style healing and have no problems. The only problem I've had was while learning the style I was accidentally healing someone other than who I was moused over.
